More star births than astronomers have calculated
The "birth rate" for stars is certainly not easy to determine. Distances in the universe are far too great for astronomers to be able to count all the newly formed celestial bodies with the aid of a telescope. view more (2008-10-02)
The Scientific Case For Human Spaceflight
Forty years ago, on 12 April 1961, the era of human spaceflight dawned when Yuri Gagarin completed a single, 108 minute, orbit of the Earth on board Vostok 1. Exactly 20 years later, on 12 April 1981, the first U.S. Space Shuttle, Columbia, was launched from Cape Canaveral. In April 2001, the Space Shuttle Endeavour is scheduled to begin the... view more... (2001-03-30)
Dwarf galaxies need dark matter too, U-M astronomers say
Stars in dwarf spheroidal galaxies behave in a way that suggests the galaxies are utterly dominated by dark matter, University of Michigan astronomers have found. view more (2007-10-25)
Light echoes whisper the distance to a star
Taking advantage of the presence of light echoes, a team of astronomers have used an ESO telescope to measure, at the 1% precision level, the distance of a Cepheid - a class of variable stars that constitutes one of the first steps in the cosmic distance ladder. view more (2008-02-11)
Peruvian citadel is site of earliest ancient solar observatory in the Americas
Archeologists from Yale and the University of Leicester have identified an ancient solar observatory at Chankillo, Peru as the oldest in the Americas with alignments covering the entire solar year, according to an article in the March 2 issue of Science. view more (2007-03-02)
Stars stop forming when big galaxies collide
Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper to be published in a November 2008 issue of The Astrophysical Journal Letters. view more (2008-10-08)
Dark and distant heavenly bodies revealing the secrets of star and galaxy formation
British astronomers are releasing the first data from the largest and most sensitive survey of the heavens in infrared light to scientists across Europe. view more (2006-07-24)
International team establishes unique observatory in Antarctica
A team of scientists representing six international institutions, including Texas A&M University, has succeeded in reaching the summit of Antarctica - also a monumental achievement for ground-based astronomy -- to establish a new astronomical observatory at Dome Argus on the highest point of the Antarctic Plateau. view more (2008-02-04)
2 unusual older stars giving birth to second wave of planets
Hundreds of millions - or even billions - of years after planets would have initially formed around two unusual stars, a second wave of planetesimal and planet formation appears to be taking place, UCLA astronomers and colleagues believe. view more (2008-01-10)
Large binocular telescope achieves first binocular light
The Large Binocular Telescope on Mount Graham, Ariz., has taken celestial images using its twin side-by-side, 8.4-meter (27.6 foot) primary mirrors together, achieving first "binocular" light. view more (2008-03-06)
Launch Of Human Orrery
The Armagh Observatory's 'Human Orrery' is the first large outdoor exhibit in the world to show accurately the elliptical orbits and changing relative positions of the planets and other solar system bodies with time. It has been constructed with the support of the Northern Ireland Department of Culture, Arts and Leisure (DCAL) and is the first... view more... (2004-11-22)
Everyone wants gamma-ray eyes!
Even before ESA`s Integral gamma-ray observatory was launched, astronomers were competing to win time to use this state-of-the-art observatory. The Integral Science Operations Centre in Noordwijk, The Netherlands, received hundreds of excellent proposals. ESA expects Integral to revolutionise the way we think about the violent Universe.... view more... (2002-10-29)
Nanoscientists Provide New Picture of Semiconductor Material
For almost a decade, scientists thought they understood the surface structure of cubic gallium nitride, a promising new crystalline semiconductor. view more (2005-10-05)
Milky Way's fastest pulsar is on its way out of the galaxy, astronomers find
The Milky Way's fastest observed pulsar is speeding out of the galaxy at more than 670 miles a second, propelled largely by a kick it received at its birth 2.5 million years ago. view more (2006-02-16)
Quatratran - Helping to make The World a safer place
Since the development of superconducting electronic devices there has been a need to develop a three terminal transistor like device sensitive enough to measure small voltage and current signals typical of those associated with single electron and photon events. A group of researchers in the Department of Particle & Nuclear Physics at Oxford... view more... (2004-02-19)
High-energy particles from violent black holes travel to Earth
Ultra-high-energy particles from just outside enormous, active black holes in nearby galaxies travel as far as 250 million light years to make it all the way to Earth, an international team of 400 physicists and astronomers from 17 countries reports in the Nov. 9 issue of the journal Science. view more (2007-11-12)
Benchmark Survey Shows that Giant Outer Extrasolar Planets Are Rare
Astronomers who used powerful telescopes in Arizona and Chile in a survey for planets around nearby stars have discovered that extrasolar planets more massive than Jupiter are extremely rare in other outer solar systems. view more (2007-07-12)
Models show one nearby star system could host Earth-like planet
The steady discovery of giant planets orbiting stars other than our sun has heightened speculation that there could be Earth-type worlds in nearby planetary systems capable of sustaining life. view more (2006-07-25)
New rocky planet found in constellation Leo
Spanish and UCL (University College London) scientists have discovered a possible terrestrial-type planet orbiting a star in the constellation of Leo. The new planet, which lies at a distance of 30 light years from the Earth, has a mass five times that of our planet but is the smallest found to date. One full day on the new planet would be... view more... (2008-04-10)
Astronomers see faintest stars in a globular cluster
Astronomers report in the Aug. 18 issue of the journal Science seeing the faintest stars ever seen in any globular star cluster. The light from these dim stars is only as bright as the light produced by a birthday candle on the moon, as seen from Earth. The astronomers used NASA's Hubble Space Telescope. view more (2006-08-21)
